Hand Knob V1

implemented unverified

Threaded-fastener hand knob: a revolved grip (plain or star-scalloped via lobes) with a captive square-nut / carriage-neck socket under a full through bolt bore — thumbscrews, jig clamps, fence locks. The sibling replacement_knob_v1 (showcase pack) presses onto a bare shaft instead; this one turns a bolt.

Built from a real example — orbit to inspect.
